I need a list of high/super torque motor that can pull a Guarder SP170 spring. Thanks!
(I will upgrade my internals if I do put a spring that heavy so no need to freak out)

That's fine, the Systema Magnum and System A to Z will pull it. Quick question, what FPS are you looking to obtain. Please base it off of .2's even though I am well aware you will be using much heavier BB's.

Either of the systema motors gcw mentioned will do perfectly. If you can't get your hands on one of those try a g&p M180 Satan. It pulls my friend's M190. That gun isn't for airsoft game use though obviously. What exactly do you need a guarder SP170 for... Seems a little extreme for use on people...

I find it odd to see the ICS Turbo 3000 listed for use with super heavy springs, but then again, I have it in my ICS MP5 and it's still kicking year after year.

The Armature in the ICS Turbo 3000 is very high quality. The magnets are Ferrous, not Neo magneteic, though.
I do not know what the TPA is on it, but I have heard claims of this motor pulling an m190 spring.

ShS high torque motors are a good bet, also in the $40-50 range shipped. The question is what battery will pull that spring rather than what motor, because many high torque motors can do it, though overheating will be an issue on any motor at this power. Hopefully you're not planning on shooting that on full auto, both for the sake of your gun and the safety of other players. But honestly you might consider a lower spring, with an SP170 you're probably going to exceed the velocity restrictions of most fields even in the sniper category, which in most places is 600 on the high end, some fields are 500 tops.

Another suggestion, if you're really going for high power you might consider a bore-up rather than just dropping in the strongest spring it can pull. You might find a lower spring will get you the power you're looking for with less stress on the gearbox.

And lastly, is this an all out SP170 high torque you're-gonna-feel-it-when-you-get-hit build or are you using that spring for a double stroke (DSG) build?

I do agree shs is a good motor but I have heard that it can be a hit or miss with them and that lonex basically blowes everything away IMO.

But I agree whith napster, why do you need that heavy of a setup? Personally you should just go with an m130 and rhop with .30 bbs. You'll be able to hit way farther than your proposed setup.

SP170 seems really excessive and you may experience a "blow-by" effect where your compression system such as cylinder and in the hop up system itself will not be able to maintain a good seal without some mods. So you may end up shooting at the same FPS range as if you were using a SP150 spring.
Why do you need an SP170? Not being critical. Just asking since that gun will no longer be field legal in any field in the US. Only thing it will be able to do is hunt squirrels.
And as far as the motors are concerned, I have used SHS HT motors for awhile and it's a good motor as long as the heat doesn't bother you. I have switched to Lonex A2 motors and I am much happier. Seems to run cooler and I have used it to pull an SP150 with ease so an SP170 may not be a problem.
